What’s slowing me down?

The more programs you install and use, the slower your PC becomes for three main reasons.

Startup items

Many programs run automatically when you turn your PC on, significantly slowing its startup time.

Background processes

Your programs could be running in the background even when you’re not using them, hogging your PC’s memory and CPU.

Scheduled tasks

Your software often sets its own schedule and can suddenly come alive and slow down your PC.

Speed up with Sleep Mode

Our tuneup process detects performance drains and stops them for you, without making you uninstall programs or interfering with your PC

Time to sleep

Switch on Sleep Mode to freeze any program that’s slowing you down. While asleep, it won’t use up any resources.

Wake up

Launch the program you put to sleep, and let our smart algorithm automatically enable all of its background activity.

...and back to bed

Once you’re done using the program, we automatically put it back to sleep to stop it from slowing you down.

The more programs you put to sleep, the fewer you’ll have running in the background, and the faster your computer will be.

Junk programs and bloatware removal

NEWIdentifies bloatware and long-forgotten programs

Your PC could be slowed down by programs you haven’t used in ages or never wanted in the first place — trial versions, unwanted toolbars, or preinstalled software. These are a waste of space and speed, and may even be a security risk. Our new Software Cleanup feature gets rid of them once and for all.

Clean it all up

Take the guesswork out of figuring out which programs you no longer need with our cloud-based reputation and unneeded-program detection systems. If you’re afraid to uninstall, we can temporarily put files in quarantine until you decide.
